Geocode address to lat and long conversion(APP FORCE CLOSES)

Question

I am new to android development and I am developing an android app in which I am converting address to latitude and longitude. I am using geocoder. But when I call that function app force closes. This is my code snippet

public  void getLatLongFromGivenAddress(String address)
    {
          double lat= 0.0, lng= 0.0;

        Geocoder geoCoder = new Geocoder(this, Locale.getDefault());    
        try 
        {
            List<Address> addresses = geoCoder.getFromLocationName(address , 1);
            if (addresses.size() > 0) 
            {            
                GeoPoint p = new GeoPoint(
                        (int) (addresses.get(0).getLatitude() * 1E6), 
                        (int) (addresses.get(0).getLongitude() * 1E6));

                lat=p.getLatitudeE6()/1E6;
                lng=p.getLongitudeE6()/1E6;

                String lati =String.valueOf(lat);
                String longi =String.valueOf(lng);

                Log.d("Latitude", ""+lat);
                Toast.makeText(getApplicationContext(), lati, Toast.LENGTH_LONG).show();
            Log.d("Longitude", ""+lng);
            Toast.makeText(getApplicationContext(), longi, Toast.LENGTH_LONG).show();
            }
        }
        catch(Exception e)
        {
          e.printStackTrace();
        }
    }

This is my logcat
